Low quality valves corrode, stick, and leak under the pressures and chemicals used in pressure washing. Spending a few extra dollars on a quality valve prevents expensive failures and water damage on the job.\u003c\/p\u003e \u003ch2\u003eInstallation and Maintenance Tips\u003c\/h2\u003e\n\u003cp\u003eInstall valves with Teflon tape on all threaded connections. Make sure the flow direction arrow (if present) points in the correct direction. A check valve installed backward blocks all flow.\u003c\/p\u003e\n\u003cp\u003eTest the valve after installation. Check valves should hold water in one direction and flow freely in the other. Relief valves should open at their rated pressure and reseat when pressure drops.\u003c\/p\u003e\n\u003cp\u003eInspect valves regularly for leaks, corrosion, and sticking. Ball valves should turn freely with a quarter turn. If a ball valve is hard to turn, the seat is worn or corroded. Replace it before it seizes.\u003c\/p\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eHow do I know if my valve is bad?\u003c\/h3\u003e\n\u003cp\u003eCommon signs of a bad valve include leaking, failure to hold pressure, sticking in the open or closed position, and visible corrosion or damage. If the valve is leaking or not functioning correctly, replace it. Trying to fix a bad valve wastes time.\u003c\/p\u003e\n\u003ch3\u003eWhat material should I choose for my valve?\u003c\/h3\u003e\n\u003cp\u003eBrass is the standard for most pressure washing applications. It handles chemicals, pressure, and temperature well. Stainless steel is better for corrosive chemicals and extreme conditions. Poly works for cold water chemical injection where weight and cost matter.\u003c\/p\u003e\n\u003ch3\u003eDo I need Teflon tape on valve threads?\u003c\/h3\u003e\n\u003cp\u003eYes. All NPT threaded connections need Teflon tape or pipe dope to seal properly. Wrap 3 to 5 times clockwise when looking at the end of the male thread. For pressures above 3000 PSI, use pipe dope for a better seal.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer valves near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.
